Not all crib mattresses are created equal. Many mainstream options use polyurethane foam, which studies show can emit harmful chemicals called VOCs.
A study from The University of Texas at Austin found that VOCs from crib mattresses can affect air quality around sleeping infants. (Source)
The Environmental Working Group highlights that polyurethane foam can emit VOCs for years. (Source)

Meets ASTM safety regulations.

Your email support team was VERY helpful early this morning! However, there was no way to make phone contact yesterday afternoon when I was having trouble with an online order. (Just a phone message saying leave a message, or some such thing.).

Frequently Asked Questions
How does the dual-sided design benefit my child?
This means the crib mattress has a firm side and a slightly softer side. For infants, use the firm side. Once the baby is approximately one year old, turn the mattress over for a more comfortable sleep surface. Both sides are firm enough to be safe for an infant.
How do I care for the mattress?
Since we wanted to make the mattress completely plastic-free, it is not waterproof on its own. Hence we strongly recommend pairing it with the KATU Organic Mattress Protector which fits our mattress perfectly, we offer this at a discounted rate when purchasing a mattress for your ease of use
Is the mattress safe for sensitive babies?
Absolutely! In fact, more sensitive babies will benefit the most from our mattress's 100% organic, VOC-free construction and are most at risk from mainstream mattresses
Will this mattress fit my crib?
Our mattress is built specifically to fit snugly within standard US cribs, it measures 52" x 28" x 4" and weighs approximately 15lbs
How do I know this mattress is safe for my baby?
Our mattress has gone through rigorous lab testing according to CPSIA and ASTM standards. If you are curious, feel free to get in touch and we can happily share the certificates from this testing for your peace of mind

We're so confident that you'll love our products, we're happy to offer a 100-night free trial. We ask that you use a mattress protector to keep your mattress in a suitable condition during your trial period, free from excessive stains, tears, odors, or soiling.

Simply reach out to us and we can arrange the return ticket
How does the lifetime guarantee work?
KATU Organic Crib Mattresses come with a lifetime guarantee. If you ever have a product issue, please contact us immediately and we will gladly help resolve the issue. As a US-based organic brand, we prioritize solving problems quickly and keeping our customers pleased.
